Phylogenetics and the Integration of Paleontology Within the Life Sciences
Published online by Cambridge University Press: 21 July 2017
Abstract
Paleontologists rely on information from modern organisms to understand fossils, but fossils can in turn be used to more completely understand the living. This is facilitated when the fossil record is understood from a phylogenetic context. Phylogenetic analyses allow the identification of robust calibration points for molecular dating analyses, and in the absence of phylogeny, “conflicts” between fossils and molecules may arise that are based not on the data, but on methodology or taxonomic philosophy. More importantly, phylogenetic analyses using fossils can overturn evolutionary scenarios based solely on living taxa, and they can direct researchers in more appropriate directions. This is necessary if paleontology is to be fully integrated with both the Earth and life sciences.
